Time Travel: Grandfather Paradox

Показать описание

Based on our current knowledge, time only moves forward! But this video is about time travel. A classic example is the grandfather paradox, in which a time traveler goes back and kills his grandfather.

So it's as simple as... If I go back, and even just briefly interact with the world, (not necessary something as severe like killing my grandfather) I won't be going back to the world I started time traveling from.

Anyone watching this from a parallel universe?
Dunno who said it but when asked if alternate realities could exist they said “Of course. There are over seven billion existing right now on this planet.”

Consider this point of view on the Grandfather Paradox: if one ventures into the past and disrupts the chain of events leading to their own birth, it creates a divergence, a splintering of timelines. The act of eliminating the grandfather results not in self-annihilation but rather in the emergence of an alternate reality where the individual still exists. This aligns with a metaphysical interpretation that suggests the unfolding of multiple possibilities coexisting in a complex temporal tapestry.

There is a possibility that in the parallel universe this video wouldn't exist and many people wouldn't no about this paradox. So thanx for deciding to upload this video because in the parallel universe I wouldn't know about this.

If we consider travel back in time as possible, then Novikov's principle of self-consistency would be the only solution to the grandfather paradox to have a logical coherence, as the multiverse-based solution generates grandfather paradoxes in turn.

Well, that one can spark some great debate.. I know it got me going.. thanks again I am loving these time videos..

Thank you for this video. Waiting for this video from a very long time.

I think that if it were possible to get in front of your grandfather's image you would not be able to kill him because he would only be a hologram.

What happens if your grandfather kills you? Does you dead body exist when you are born? Forgetting some of the math here .

Ok so I have a question, just to make sure I got this right.
You go back in time, kill your grandfather, and that creates a branch timeline in which your parents and you don't exist but the timeline in which you are from still does right? That's the entire point of you being the paradox correct? Since you're basically existing in a timeline you created that you don't exist then buy lo and behold, there you are.
Second question to that, would you even be able to return to the timeline you came from? Or when you travel to the present, it's only the present timeline of the timeline you just created?

I believe you can go backwards in space-time, the problem is that going back one day in time, I believe, will cause us to quantum tunnel in a random direction within 1 light day of Earth (25, 902, 068, 371.2 kilometers). Even if we shoot a powerful laser beam at the Earth, we will not be able to change our past in time. And so the grandfather paradox can be easily explained. You can go back in time, but the farther you go back in time, the farther you will be from where you started your journey.

When did you do this experiment and show me your mathematic.
Well.. I'm still waiting.

Is that mean that I am in this time because neither me nor any body went back and made the future (wich is this time) collapse... This very similar to double hole electron experiment.... When you change something the wave nature collapses

Cmon guys. As nerds we were taught since birth that the universe doesn't store time memory. (not like you can just press <RWD button on the tape and go back) Everything that messes with time is either parallel, or at the cost of structures. You can only really travel to the future and even that would be costly. Quantum mechanics is just a different chaotic universe by itself, out here things are just boring. =/
